Rihanna Ordered To Cover Her Nipples

Rihanna loves to be nekkid … A LOT … but Instagram says her displays of public nudity go way too far — and is now threatening the singer within an inch of her exposed nipples.

Rihanna posted topless snaps Tuesday from her photo shoot with Lui, a French skin magazine — and within an hour Instagram yanked them down … because they violated rules against nudity.

Our Instagram sources tell us Rihanna got an email that basically warned her … keep your clothes on or risk having your account permanently shut down.

But like a bikini trying to contain her boobs — IG couldn’t stop RiRi … and she just posted the banned nudes on Twitter instead.

Thank you, Twitter.
